Background

China has great technological progress, products of all walks of life are continuously updated and upgraded, the afternoon nap chair is still in the exploration stage, and mature afternoon nap chairs cannot be seen in schools and markets. For example, a enjoying interest brand multifunctional folding noon break deck chair has five functions, is comfortable to lie and sleep, but is not suitable for serving as a chair for students, b builds a desk and chair of a changeable noon break bed developed by Cheng education, is of a desk and chair integrated type, has the defect of occupying too much space unless the number of students in a classroom is reduced, c is a single lifting student desk and chair recently released by Guangzhou European Ge furniture company Limited, is the best noon break chair at present, is attractive and practical, but has several defects: 1. the desktop is required to be lifted every day, the chair seat is reduced, the operation trouble is increased, 2, the foot isolation plate is required to be placed below the desk, the lying and sleeping direction is limited, the vertical space size is increased, the containing capacity of a classroom is reduced, 3, the foot isolation plate is required to be stored every day, then the foot isolation plate is clamped and placed below the chair, the protruding bayonet component is exposed outside after the foot isolation plate is pulled out, and certain attractiveness is affected.

Sleep is an important link for restoring, integrating and consolidating the memory of an organism and is important for promoting the brain development, the bone growth, the eyesight protection, the physical and mental health and improving the learning ability and efficiency of primary and secondary school students. In order to implement the sleep command of the education department, some places actively act, some places have high-quality noon break for ten civil projects, but the places of schools, teachers and materials and the like are limited, so that the noon break becomes a bottleneck of implementation, and people expect an appliance, namely a siesta chair, which can improve noon break without moving tables and chairs or vacating a sleeping room in a classroom and adding a bed.

Society needs afternoon nap: the urbanization scale of China is getting bigger and bigger, the residence, the workplace and the school are generally distributed more and more widely, as long as one of the places is far away from the other place, students are difficult to get back to home for rest at noon, except for a part of private schools and loose county school, most of students can only lie on the eyes of a desk and a mike at noon, and can lie flat for sleeping, so that the students become a luxury, and people put out efforts for the people to improve measures as much as possible and continuously feel grope, for example, the new western security, namely three thousand students are uniformly prescribed by the school to fall asleep on the desk; the Shandong Zhaoyong committee calls for pupils to sleep recumbently and starts to be popularized from a test point of a Pingyin experimental school, and once the students reach a noon classroom, the students push desks and chairs to put on a yoga mat; in order to avoid moving desk and chair, the students of Hangzhou university attach to tide primary schools and the like, the students want to improve the desk top and pull out the pedals to form an integrated desk and chair which can be laid down for sleeping.

The exploration way of the afternoon nap chair: the chair is one of the most intimate and longer-service-time articles in life, has a plurality of types, but the chair can be used for sleeping while being used for providing a stool, and the number of the articles is very small, so that the inventor who relates to the field of afternoon nap chairs for decades is not enough for 30 people, the invention content belongs to auxiliary functions, and if the problems of warm keeping, swinging and transverse splicing are solved, the designs are heavy, or the structure is complicated, so that the practical requirements are difficult to meet. And mature folding deck chairs, folding beds, accompanying noon break chairs and computer chairs in the market are not single in function, or occupy too large space, only a few computer chairs can help adults to have a nap but cannot walk into a classroom, if the design of a student noon break chair is finished, simplicity, quality, safety and production cost reduction are considered: 1. the functions of the seat and sleeping in the bed must be simultaneously considered, 2, the appearance of the seat must be coordinated with classroom environment and history, 3, the existing desk and chair cannot be moved, a bed or a bedding cannot be additionally added, 4, children can convert the functions by themselves without any tool, 5, the seat is suitable for the crowdedness degree of different classrooms of different schools, and 6, the seat can be preferably conveniently piled up, folded and stored.

Detailed Description

The problem of the student's afternoon nap is solved according to the specific situation of the school, the classroom of the public school in the city is usually tense, the space is particularly narrow after the student puts down the desk and chair, the hidden bed cabinet arranged near the wall has no space, the afternoon nap bar is difficult and serious to reform by using reading rooms, gymnasiums, ball rooms and the like, 1 is not enough, 2 is troublesome to change day by day, namely, the classroom cannot move the desk and chair easily day by day, and the only thing that can be hoped is to make an article on the stool and chair.

Implementation of the multifunctional afternoon nap chair: the adjustable plastic back frame is composed of a foot rest 1, an L- shaped seat frame 2 and 3 main parts of an adjustable back frame, and is produced by plastic mold opening and assembled by a plate shell structure matched with 2 hardware hinges.

Switching from seat to couch function: a student lifts the L-shaped seat frame 2 to a gap below a back plate 2-b of the L-shaped seat frame 2 by hand and turns over the L-shaped seat frame 2 outwards for 180 degrees, pulls the adjustable back frame 3 forwards for about 15 degrees and then puts the adjustable back frame flat backwards, lifts the adjustable back frame to a desired inclination, pulls out the telescopic footrest 8 according to stature and adjusts the height of the telescopic pillow 4, and can lift and put the footrest flat according to requirements.

From couch back to seat: when the hand rest is arranged, the left and right folded edges of the hand rest are slightly unfolded outwards by hand and then are put down, the telescopic footrest 8 is pushed, the L-shaped seat frame 2 is lifted up and turned over for 180 degrees backwards, the adjustable back frame 3 is lifted up to abut against the L-shaped seat frame 2, and if the height of the telescopic pillow 4 needs to be adjusted, the positioning beads 11 are pressed in to drag the telescopic pillow 4.

Aiming at the crowdedness degree of a classroom, two sizes can be applied: when the classroom is very narrow, the space does not allow to be completely unfolded and lie flat, only need to turn over L type seat frame 2 and put down adjustable back frame 3 again, this is exactly to lie and sleep after sitting on, people's foot still stands at this moment and does not take up too much space, though not satisfying compare lie prone on the desk still how much, must also face up and sleep, if calculate his present area of occupation of land by 7 chairs is 0.37M, when the classroom is not too crowded, can pull out the footrest and can also turn over and put the board, space increases 23% than original like this.

The principle of natural locking is realized: because the lower end of the adjustable back frame 3 is provided with the clamping type angle function hinge 10, the hinge can automatically unlock the clamping lock and lay flat backwards when the hinge needs to swing forwards for 15 degrees after being in place. If the chair is in the state, the adjustable back frame can move back and forth when touching the back plate 2-b on the L-shaped seat frame 2, the adjustable back frame 3 can be put down only when the L-shaped seat frame 2 is turned over a little forward, as long as the design is carried out, a connecting line is assumed from the middle point of the long hinge 9 on the L-shaped seat frame 2 to the center of the angle functional hinge 10, and as long as the adjustable back frame 3 is arranged vertically or is less than the connecting line of 90 degrees, the position can be naturally limited when touching the L-shaped seat frame 2 when the adjustable back frame 3 is turned over, and the locking mechanism can not be clamped and withdrawn, therefore, the chair can also be exempted.

The clutching condition of the L-shaped seat frame 2 and the adjustable back frame 3 is as follows: when the chair is in a shape, the backrest plate 2-b above the L-shaped seat frame 2 is just placed in the recess of the adjustable back frame 3, the outer surfaces of the backrest plate and the adjustable back frame are aligned, the placing sequence of the L-shaped seat frame 2 and the adjustable back frame 3 can be random, and the placing sequence is the same for all people, so that misoperation in switching can be avoided.

Stacking and stacking functional design: the existing school classrooms are all nervous, it is also common to move desks and chairs to achieve the effects of body movement and temporary classroom function change, at the moment, a plurality of chairs are very burdensome, a plurality of spaces can be saved by the aid of the stacking function, the disgust feeling can be greatly relieved, and particularly, the trouble is saved in the carrying process.

Designing a hand placing plate: the upper part of the folding hand board is connected with the upper end thin part of the foot rest by replacing a hinge with the plasticity of PP folding glue, the left folding edge and the right folding edge are automatically clamped when the hand board is folded for 90 degrees and is horizontal through the increment of the edge of the foot rest after being folded, and the hand board can be easily put down only by slightly unfolding the two side edges with hands and then pressing the two side edges outwards.

Design about adult L type net frame: the chair is only suitable for middle and primary school students, the size of the chair can be enlarged to be made into an adult afternoon nap chair, the seat plate 2-a and the backrest plate 2-b are changed into the ergonomic soft cushion chair with the adult L-shaped mesh frame 12, the number of white-collar people in China cities is large, the office space and the functions of the chair are limited, many employees still have to lie on the table to have a rest, although a large-angle lying and sleeping function is added to an individual computer chair, the computer chair is also insufficient, 1, the lying and sleeping angle is too small to meet the ideal requirements, 2, handrails are generally arranged, the entering and exiting of the body can be influenced for crowded offices, 3, the production price is too high, 4, metal parts are heavy, 5, five-star feet are limited in diameter and are not stable enough to fall down, the handrails are not too inclined, and 6, stacking and carrying is not facilitated. The multifunctional all-plastic afternoon nap chair can make up for the defects and can be used as a chair of another style to appear in an office.

The adult L-shaped mesh frame 12 is only replaced by replacing the seat plate 2-a and the back plate 2-b with mesh frames, and is characterized in that the contact surfaces of the seat plate 2-a and the back plate 2-b with people are designed into curved surfaces according to human engineering, and the lower bottom layers are flat and are respectively placed on the sleeping plate 2 of the foot stand 1 and the back section sleeping plate 5 of the adjustable back frame 3. After being folded for 180 degrees, the exposed back section sleeping board 5, the sleeping board 6, the inner layer sleeping board 7 and the telescopic footrest 8 are all stuck with flocking cloth, which not only softens the sleeping mat, but also neatly draws a color.
